These models are 500 Watt, single output, series pass regulated power
supplies, with an internal GPIB interface and SCPI programming. These
models provide many talker/listener functions including remote programming
of voltage and current with feedback of actual measured output values.
16 supplies can be connected to one GPIB interface via a serial link connection.
